SSLError: [SSL: EE_KEY_TOO_SMALL] 在 Ubuntu 上启动 jupyter notebook 时 ee 密钥太小 (_ssl.c:4022) [英] SSLError: [SSL: EE_KEY_TOO_SMALL] ee key too small (_ssl.c:4022) on Ubuntu when starting jupyter notebook

问题描述

当我尝试通过 EC2 服务器在 Ubuntu 中启动我的 Jupyter Notebook 时遇到此问题.

I have this problem when I am trying to initiate my Jupyter Notebook in Ubuntu over the EC2 server.

SSLError: [SSL: EE_KEY_TOO_SMALL] ee 密钥太小 (_ssl.c:4022)

SSLError: [SSL: EE_KEY_TOO_SMALL] ee key too small (_ssl.c:4022)

原来我有

权限错误 [Errno 13]

permission error [Errno 13]

然后我关注了这个页面并通过将 /home 文件夹和 ~/.local/share/jupyter/ 文件夹的所有权更改为当前用户来修复它.

then I followed this page and fixed it by changing the ownership of the /home folder and ~/.local/share/jupyter/ folder to current user.

现在我遇到了 SSL 问题.我按照建议查看了这个链接，但没有运气.

Now I have the SSL issue. I checked out this link as suggested, but no luck.

然后我 cd 到我的 certs 文件夹，mycert.pem" 就在那里.而且我确定我用 "https://" 替换了本地主机 IP 地址.亚马逊网址.

I then cd to my certs folder, the "mycert.pem" is there. And I am sure I replace the local host IP address with "https://" amazon url.

我的错误代码似乎与此帖子不相似 也是，虽然我们的密钥都太小了.但是我的是"ee key"，还有"_ssl.c:4022"，和他们不一样.

My error code seems not similar to this post too, though we both have key too small. But mine is "ee key ", and "_ssl.c:4022", which is different from them.

整个错误信息是这样的:

The entire error message is like this:

推荐答案

cd 到您的 cert 文件夹，然后输入以下命令:

cd to your cert folder, and type this command:

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout mycert.pem -out mycert.pem

你是对的，将你的 rsa 增加到 2048，这将解决你的问题.至少这解决了我的问题.

You are right, increase your rsa to 2048, this will solve your problem. At least this solved mine.
